    摘要： A pyrimidinedione derivative compound has a basic backbone in which a phenyl group part and a pyrimidinedione part are linked by a linking structure comprising an alkyl chain containing two nitrogen atoms. This linking structure is represented by ##STR1## [wherein A is --(CH.sub.2).sub.n --, --CO-- or --O--(CH.sub.2).sub.m --; each of R.sup.1 and R.sup.2 is independently a hydrogen atom or a lower alkyl group which may be substituted by a hydroxyl group, or R.sup.1 and R.sup.2 may be so linked with each other as to make an alkylene chain and thus form a heterocyclic structure; R.sup.5 is a halogen atom, a hydroxyl group, a lower alkyloxycarbonyl group, a lower alkyloxy group which may be substituted by a lower alkyloxy group, or a lower alkyl group which may be substituted by a hydroxyl group, or R.sup.5 may be so linked with R.sup.1 as to make an alkylene chain and thus form a heterocyclic structure; n is 0, 1, 2 or 3 (when R.sup.5 is the hydroxyl group, n.noteq.0); m is 0, 1, 2 or 3; and k is 0, 1, 2 or 3 (however, a compound in which A is --O--(CH.sub.2).sub.m -- and R.sup.5 is the hydroxyl group is excluded from the pyrimidinedione derivative)]. The pyrimidinedione derivative and its acid addition salt are useful for a medical treatment of cardiac arrhythmias.

    摘要： The invention relates to a preparation process of aliphatic polyester, comprising using an ion exchange resin as a drying agent and after the dehydration polycondensation reaction, regenerating and drying the used ion exchange resin and repeatedly using said ion exchange resin in the next dehydration polycondensation reaction, in a process for preparing aliphatic polyester from one or more aliphatic compound (A) by heating in an organic solvent in the presence of a catalyst, distilling a generated water containing organic solvent out of the reaction system, treating the distilled organic solvent with a drying agent, and returning the treated solvent to the reaction system to progress a dehydration polycondensation reaction. The process of the invention enables one to steadily and efficiently prepare in industry an aliphatic polyester having an excellent color tone, high molecular weight and high quality.
